“…The clear voice of the tutee agent comes from the fact that it was computer-generated synthetized voice which has less noise compared to recorded human tutee voice. However, studies related to the agent voice in the education field found a small effect of various kinds of pedagogical agent voices on recall performance (Morris & Chen, 2021), whether modern synthesized voice or the classic synthesized voice.…”

Video is the most widely used format to deliver a lecture by the tutor/lecturer in electronic distance learning. One of the video presentation styles is a dialogue style where the learning material is presented with a dialogue between a tutor/teacher and a tutee student. The presence of the tutee and dialogues provide cues that enable the observer student to pay more attention to the video. However, most video lectures available are in a monologue style. The authors developed a system that transforms a monologue-style lecture video into a dialogue-like video style by adding a synthetic tutee agent. They conducted a within-subject design experiment involving first-year undergraduate students comparing this dialogue-like video style with other two traditional video lecture styles, the monologue, and dialogue styles. The evaluation found that students perceived the dialogues in the dialogue and dialogue-like style supported them to have a better learning experience. The finding indicates that this dialogue-like video style has a comparable effect on the traditional dialogue video.

“…Participants were unable to rewind, pause, fast forward or skip any part of the recording. Prior to each audio segment, participants were asked to memorize a 5-digit number to simulate the cognitive stress and load in a natural learning environment (Morris & Chen, 2021). This task was designed based on Miller's Law, which states that the working memory can hold approximately 7 (plus or minus 2) discrete objects or chunks (Miller, 1956).…”

Screen Reader Voices: Effects of Pauses and Voice Changes on Comprehension

This study seeks to investigate the effects of manipulating aspects of a text-to-speech (TTS) voice on the learning and comprehension of a short passage, as well as detection of aspects of the passage such as its organization and key information. Pauses and pitch changes were used to demarcate this type of information. Participants listened to the passages and answered a series of cued and uncued recall questions to measure comprehension and learning, followed by a task to identify header structure. Preliminary results show trends that adding pauses might be beneficial, but more participants are needed to provide conclusive evidence. This study will contribute to the body of research surrounding technology adoption, assistive technology, and how to improve AI voices for the purposes of learning, as well as our understanding of how we process auditory information.
